Abstract (en)

[origin: EP0558428A1] Toroidal transformer (1) for class A differential sensor. The secondary winding (6) is coiled around only a sector of the first insulating casing (5), of angle (A) for example of the order of 180 degrees. The second insulating casing (7) consists accordingly of two nested half-sectors (7A, 7B), thus leaving free a part (5S) of the first insulating casing (5) around which the primary winding (SP, SN) is then coiled. The proportions of the transformer assembly are thus reduced. <IMAGE>
